👀Worth noting:
Simulating waves in just V1 had an effect on all sensors—even the ones far away. This shows how localized TWs can create widespread patterns in MEG/EEG.

🔍Proof of concept:
We used visual stimuli carefully designed to elicit traveling waves in V1. Participants viewed these while we recorded simultaneous MEG/EEG, giving us a ground-truth dataset for detecting traveling waves.

💡Our solution:
Using an encoding model, we simulate traveling waves in V1 → project them into sensor space → generate predicted MEG/EEG signals.
